Flexslider using cropped images

Hi,

I installed a theme called CreativePearl from Themeforest. I am having an issue with the FlexSlider on the front page, and since the theme designer is hopeless in responding to emails I’m posting here hoping to get a little help.

The slider is calling images at 1480x427px even when uploaded at other sizes. Example:

https://danpowerphotography.com.au/wp-content/uploads/2013/10/120830_treble-cone_1321.jpg – original upload
https://danpowerphotography.com.au/wp-content/uploads/2013/10/120830_treble-cone_1321-1480×427.jpg – slider source image

I want the slider to load the originally uploaded image, not the cropped image. I have modified the CSS to make this work (changing the image URLs in firebug works perfectly) but I cannot find where the slider is loading the 1480×427 images instead of the originals.

Can anyone help?

Thanks!
